CAREUEETEB CONTROL.

Application filed January 24; 19530.

T 0 all whom it may concern:

Be it known that 1, WILLIAM D. iVl-innnn, a citizen of the United Statesof America, residing at Columbus, in the county-of F ranklin and Stateof Ohio, have invented certain new and useful Improvements in CarbureterControls, of which the following, is a specification.

My present invention relates to a well known type of automobile whosecarbureter is commonly controlled by a rotatable button on the dash asto its working mixture, and whose air supply to the carbureter can bechoked for a rich starting fuel, by means of a choker rod extendingforwardly through the radiator so as to be accessible to the oper-.

ator when cranking the engine by manual operation of the usual startingcrank.

Where an automobile of this type is pro vided with a self starter of anyknown construction, it is obviously desirable to be able I of theconnections, and v Fig. 6 is a face view of the control button.Referring now to these figures .I have to operate the choker valve fromthe dash, and to do this ordinarily requires a separate dash control,involvinggreater complications and additional boring of the dash board.

My present invention aims to accomplish the above by the provision of adash carried control member movable toward and away from the dash forcontrol of the choker valve, and rotatable for control of the needle ormixture regulating valve, together with connections permitting controlof each valve by the respective movement of the control member,independent of, and without effecting, the other valve.

vlVith. these objects in mind, the following description ofmy inventionwill be better understood in its reference to the several parts shown inthe accompanyingdrawing. This drawing forms apart of the followingspecification and includes several figures of which,

Figure 1 is a vertical longitudinal section illustrating the practicalapplication of my invention,

hicle, of which portions 10 is the dash board and 11 the instrumentboard, both of which form parts of the dash as a whole, and the latterof which more particularly supports the usual indicatin instruments andthe like shown. in Fig. 3, including a speedometer l2 and a controlmember having a button The carbureter is generally indicated 1%, havinga valve 15 in its air supply, for the control of which the usual chokerrod extends forwardly through the radiators *rearwardly inclined'anglethrough the dash board 10 and is in accordance with my present inventionprovided with a laterally pro jecting pin 22 at its upper rear end asseen most clearly in Fig. 5, this end of the rod b ing'axially shiftablein a sleeve 23 through a lengthwise slot 2d of which the pin 22 0.;-tends, so that the rod section 19 is thus rotatable with the sleeve 23although it permits the latter to shift lengthwise thereof withoutactuation of the mixture regulating valve. The choker rod 16 isconnected to one of a bell crank 25 on the stem of the choker valve, theother arm of which is in accordis connected to one arm of a bell crank27. To

the other arm of the last mentioned bell crank is connected one angularend 28 of a connecting rod 29 whose opposite end is extended through,and adjustably connected to, a set collar 30 swiveled in connection witha yoke 81. This yoke has apertured extensions between which the sleeve23 is lengthwise disposed, the upper section 19 of the mixturecontrolling rod passing loosely through one apertured extension, and thelower forward end of the stem 32 of the control member passing looselythrough the other aperturcd extension of the yoke and into one end ofthe sleeve 23 in which it is securely fastened by aset screw 33.

The upper rear end of the stem 32 is rigidly connected to the controlbutton 13 through the extensions of yoke 31.

In a similar manner when a rich starting fuel is desired, the but-ton 13is pulled up wardly and rearwardly and it is thus obvious that thismovement will be communicated tothe yoke 31 in View of the dispositionof sleeve 23 between portions of the yoke, and will thus be communicatedthrough the rod 29, bell crank 27, and rod 26, to the bell crank 25 ofthe choker valve. It is likewise obvious that this latter movement willnot effect the mixture regulating valve connections in view of the factthat rod section 19 slides in the sleeve 23.

In this way my invention permits of independent control of the chockervalve and the mixture regulating valve from the same control member sothat with machines having self starters, whereby dash control of bothvalves is highly to be desired, if not essential, such. control may bereadily accomplished without additional boring of the 'instrument boardand without duplicating.

the control member as is nownecessary.

I claim:

1. An automobile havinga carbureter pro-' vided with a mixtureregulating valve and an air supply provided with a choker valve, controlrods movably connected to the said choker valve and thesaid regulatingvalve,

a yoke carried by the rod of the chocker valve, having aperturedextensions through one of which the rod of the regulating valve isrotatable, a control member includinga button and a stem, the latter ofwhich is rotatable through the other yoke extension, a'sleeve disposedbetween theextensions of the yoke member and within one end of which theadjacent end of the control stem is secured, said sleeve having alengthwise slot and slidably receiving in its opposite end the adj acentend of the rod of theregulating valve, and a pin projecting from the rod-of the regulating valve through the slot of the sleeve for the purposedescribed.

2. An automobile having a carbureter provided with a mixture regulatingvalve and a choker valve, arotatable rod movably connected to theregulating valve, a'lengthwise shiftable rod movably connected to thechoker valve, a control member including a button and a stem mounted torotate and shift in the direction of its length, and connections betweenthe said stem and the rods of the choker valve and regulating valvearranged to communicate lengthwise movements of the stem to theformerand rotating movements of the stem to the latter, said connectionsincluding a yoke carried by the choker valve rod, and a sleeve withinand movable with the'yoke to which the stem is .connected, and in whichthe rod of the regulating valve is slidable and non-rotatable.

3. A device of the character described comprising a. control rod in twoaxially 'alined sections, a connection between said sectionsincluding asleevesecured' to one section and having a slidable and non-rotatableconnection with the other section, a yokehaving apertured extensionsthrough which said sections are rotatable and between which said sleeveis positioned, and a second control rod connected to said yoke, as andfor the purpose describedu 4:. A device for use in connection with anautomobile having a carbureter provided with a mixture regulating valveandan air supply having a choker valve, said device comprising controlrods operatively connected to the said choker valve and the saidregulating valve, the control rod of the regulating valve having acontrol button at one end and being in two axially alined sectionsslidable relatively to one another and constrained to simultaneousrotation, a yoke having extensions through which said rod sections arerotatable, a sleeve within the yoke around the adjacent ends of the rodsections and connected to one of the rod sectionsto engage and move theyoke when the last mentioned r'odsection is shifted in the direct-ion ofits length, and a swiveled connection between the choker valve controlrod and the said yoke, as described.

5. The combination with a carbureter including a choker valve and a fuelvalve, of

-a control rod mounted for longitudinal and rotative adjustment andhaving connections .to said control valve and fuel valve including auniversal joint, a bell crank lever, a

link connecting one arm of said lever to said.

choker valve, and a link connected to the other arm of said lever and.having aconnection to said control rod permitting relative movementthereof whereby said choker valve is actuated by the longitudinalmovement of said control rod and said fuel valve is adjusted by therotative movement thereof.

In testimony whereof I aflix my signature.

WILLIAM D. WARNER.
